Abstract: Nine compounds, atranorin, chloratranorin, lecanoric acid, ethyl orsellinate, orsellinic acid, methyl (3-orcinolcarboxylate, divaricatinic acid, divaric-atic acid, and methyl hematommate were isolated from Parmelia tinctorum Despr. Their structures were determined by the spectral data analysis. The essential oil and concrete from P. tinctorum were analyzed individually by means of GC & GC/MS/DS. Thirty-seven compounds were identified quantita-tively and qualitatively in the concrete, the main compounds are ethyl hematommate, methyl j3-orcinolcarboxylate and ethyl orsellinate. Fortyseven compounds were det-ermined quantitatively and qualitatively in the essential oil.
